About International table BTU per cubic foot
The international table BTU per cubic foot (BTU(IT)/ft³) equals 1055.05585262 J / (0.3048)³ m³ ≈ 37258.95 J/m³. Standard in US and Canadian gas industry for expressing the gross calorific value of natural gas as distributed (pipeline quality gas ≈ 1000 BTU/ft³). 1 BTU(IT)/ft³ ≈ 37.26 kJ/m³ ≈ 10.35 Wh/m³.
About Kilojoule per cubic metre
The kilojoule per cubic metre (kJ/m³) equals exactly 1000 J/m³. Common in gas industry and HVAC for expressing the volumetric heating value of fuel gases: natural gas ~35-38 MJ/m³, biogas ~20-25 MJ/m³, hydrogen ~10.8 MJ/m³ (standard conditions). 1 kJ/m³ = 1000 J/m³ = 1 Wh/(277.8 m³).
